S1RA | Selective sigma-1 antagonist

S1RA (E-52862, 1265917-14-3) is a potent and selective σ1 antagonist with weak binding at σ2 (IC50 σ1 = 17nM, σ2 = 9300nM).1,2 S1RA abolished mechanical and thermal hyperalgesia in mice with carrageenan-induced acute inflammation by enhancing the action of endogenous opioid peptides of immune origin in a σ1 dependent manner.3 BD1063 potentiated µ-opioid antinociception in mice in a σ-dependent manner.4 S1RA displayed neuroprotective effects in a mouse model of ischemic stroke.5
